Mira Mesa arson victims have died

MIRA MESA  A mother and daughter gravely injured in an arson fire at their Mira Mesa home on Thursday died Friday afternoon, a San Diego homicide lieutenant said.

The mother’s son who was jailed in the incident now faces two murder charges, Lt. Jorge Duran said.

Bouakham Sphabmixay, 69, and her daughter Pamela Sphabmixay, 48, were taken off life support at separate hospitals, and both died about 4 p.m., Duran said.

They were in their Featherhill Lane house with a male renter when the blaze broke out about 1:30 a.m. Firefighters doused the blaze in an upstairs room and found the women unconscious. The renter got out with a minor injury.

Thongsavath Sphabmixay, 44, was arrested at the scene on suspicion of three attempted murders and arson. Duran said two of the charges would be changed to murder.
